CURTAIN-FASTENING.

Specification of Letters Patent.

Patented Jan. 15, 190'7.

Application flled July 2l, 190B. Serial No. 327,179.

To a/ZZ whom, it may concern:

Be it known that I, IcNATIUs V. Frsrnn, a subject of the Emperor of Austria-Hungary, and a resident of Stoneham, in the county of Middlesex and State of Massachusetts, have invented new and useful Improvements in Curtain-Fastenings, of which the following is a specification.

My invention relates to fastenings for curtains, carriage-top flaps, and the like; and it consists in certain improvements in con-,

struction herein to be described.

In the drawings hereto annexed, Figure l is a vertical cross-section of my curtain-fastening in its normal position. Fig. 2 is a similar cross-section showing the mode of disengaging the fastening. Fig. 3 is a similar cross-section showing the fastening in position to permit withdrawal or disengagement of the curtain, and Fig. 4 is a section on line 4 4 of Fig. 3.

The support for the fastening consists of the post A, which is screwed or otherwise secured to any appropriate base, as D, which may form part of a carriage or other structure. In the preferred form shown the post A is hollow and substantially in the shape of a small square box, open at the top, whereof the sides a2 are of full height, the side a but slightly c ut away, and the side c considerably reduced in height to admit the fastenerhead and allow it to assume a position between the sides c2. The sides c2 are perforated to admit a transverse pin P, which is preferably secured by riveting. The head B is of proper proportions to serve as a fastening-button when placed with its axis transverse to the aXis of the post A. This head B has a notch b near one end thereof, formed between the outer projection b5 and the inclined base t7, the said base 57 being inclined upward toward the said notch b.

A curved slot having terminal portions b2 b* and a middle portion b3, the latter substantially parallel to the inclined base b?, is formed in the head B and is of proper proportions to admit the securing-pin P. tg?- The above-described fastener will in most cases be found entirely operative without the employment of any retaining-spring; but I prefer to place a spring, as S, in the socket formed by the boX shape of the post A, so that this spring by bearing upon the opposed portion of the head B will tend to retain it in whatever position it may be placed.

C indicates the curtain or similar object, which is perforated, so as to slip over the post A and be retained there by the head B. The fastening should be so placed in its support D that the strain on the curtain-flap or similar object is borne by that side of the fastening remote from the notch t when the head B is in the position shown in Fig. l. The pressure of the curtain C against the overhanging portion bo of the head B tends to press the head upward, and this pressure serves to hold the head secure in its transverse locking position, the pin P acting as a fulcrum and pressing the base of the notch b firmly down upon its bearing a. As the only Way to disengage the fastening is to move the portion b both inward toward the post and downward, the presence of the curtain C by opposing such movement tends to hold the fastening in proper position, and this, if need be, without the employment of any holding-spring, as S.

In order to disengage the fastening orto prepare it for the reception or withdrawal of the curtain C, all that is necessary is to press upon the overhanging part b, so as to start the head B to the position shown in Fig. 2, and then continuing this movement the head, guided by the pin I and the slot, is turned to the position shown in Fig. 3, when if a spring, as S, be employed it will be held in position by the spring. When the aXes of the head B and post A are substantially coincident, as in Fig. 3, the curtain C can either beslipped off or put on, and when put on the fastening is accomplished by tipping and depressing the head B to bring it into the position shown in Fig. l. I

What I claim, and desire to secure by Letters Patent, isp l. In a fastener the combination of a post, a head mounted on the post and formed with a notch and a base inclined toward the bottom of the notch, a pin passing transversely through the post, the head provided With a curved slot embracing the pin and approximately parallel to the inclined base at its middle portion, the post being made with a bearing to occupy the notch When the head is transverse tothe post, the side of the head farthest from the notch overhanging the post.

2. In a fastening the combination of a post, a head formed with a notch and a base inclined toward the bottom of the notch, a pin passing transversely through the post, the l head provided With a curved slot embracing IOS IIO

the pin, and approximately parallel to the inclined base at its middle portion, the post being made With a bearing to occupy the notch when the head is transverse to the post, the side of the head farthest Jfrom the notch overhanging the post, a socket in the plosf;l and a spring therein to bear against the 3. In a fastening the combination of a. ost, formed in boX shape having one side o the boX cut away to admit a head, the head formed With a notch and a base inclined toward the bottom of the notch, a pin passing transversely through the post, the head provided With a curved slot embracing the pin L5 and approximately parallel to the inclined vbase at its middle portion the post being IGNATIUS V. FISTER.
